Detailed Description

Overview

The GPIO Driver Library allows full configuration of the MSPM0 GPIO module. The GPIO peripheral provides the user with a means to write data out and read data in to and from the device pins. It also provides a way to detect wakeup events while the device is in a low power state.

[in]	pins	Valid options will depend on index argument. When index == DL_GPIO_EVENT_ROUTE_1, valid pins values are bitwise OR of DL_GPIO_PIN (0-15). When index == DL_GPIO_EVENT_ROUTE_2, valid pins Bitwise OR of DL_GPIO_PIN (16-31).
